Self-Supporting Insulated Overhead Wire Cable SIP-4 (2X16, 4X16, 4X25, 4X35)​ The Self-Supporting Insulated Overhead Wire Cable SIP-4 stands as a robust solution for efficient power distribution, available in versatile specifications: 2X16, 4X16, 4X25, and 4X35. Designed with a self-supporting structure, it eliminates the need for separate messenger wires, simplifying overhead installations across urban, rural, and industrial landscapes.​ Crafted with high-conductivity aluminum conductors, the SIP-4 cable ensures low power loss and reliable performance in low-voltage networks (typically 0.6/1kV). Each conductor is insulated with premium materials like XLPE or UV-stabilized PVC, offering exceptional resistance to weather, moisture, and UV radiation—critical for enduring outdoor conditions. The self-supporting design integrates strength members within the cable structure, enabling it to bear its own weight and environmental loads, such as wind and ice, without additional support.​ Available in 2-core and 4-core configurations (2X16 to 4X35), it caters to diverse power demands: from residential neighborhoods to commercial complexes and light industrial facilities. The 2X16 variant suits smaller-scale applications, while 4X35 handles higher loads, ensuring flexibility for project-specific needs. Compliance with international standards (e.g., IEC 60502) guarantees safety, compatibility, and durability, making it a cost-effective choice for infrastructure projects prioritizing efficiency and longevity.​ Its insulated design minimizes the risk of short circuits and electrical hazards, while the self-supporting feature reduces installation time and labor costs. Ideal for areas where traditional overhead lines are impractical, the SIP-4 cable delivers consistent performance, making it a trusted asset for modern power distribution systems.
